Hill Top Farm is a particularly sensitive restoration of the listed building using traditional materials and techniques married to the integration of advanced renewable energy measures and thermal strategy. Its success lies in the combination of solar panels, wind turbine, natural wool insulation and lime render with more innovative measures such as an intelligent heating system, underfloor heating and sunpipes, all within the context of a listed building whose architecture has evolved over the centuries. This project embodies best practice and should be seen as a model for combining innovation and sustainable construction practices with conservation of our historic built environment. That the elements are discrete, restrained and work together in harmony is further testament to its success
